Review Image by Masterlee253 Masterlee253
Because a local HVAC company installed my heatpump last week, a tech came out to install this thermostat free of charge minus my involvement in completing the installation wirh providing my Internet designation and password. The installation process was seamless and smooth. I can monitor the heatpump functions from anywhete now. I can also see the current temp away from the wall as the digiral temp display is large and stays lit. This thermostat is smart as it calibrated the temp setting we set and AI does the rest by communicating with me. I bought the back plate separately from Amazon (black) and it is very pleasing to look. Its too early to talk about the longevity of the system but it is functioning beautifully at this time. It is fully capable of accommodating one's individual scheduling but I programm it to have it at constant 72 degrees. This us todays kind of thermostat! ... show more

Coming from the Nest, this was a breeze to install. I like that it comes with label stickers. Its clearly well thought out when it comes to installing. Setup and configuring on the network was also quick. Overall it took 20 minutes between removing the old one and installing Ecobee. I think the only thing to mention is that make sure you strip the wire back enough and insert it in fully. Mine were not making contact as much as I thought I did so had to re strip the wires. Other than that. Functionality wise its better. Home assistant integration is smooth. This works very well for those with multi split zones. Other than that. Its controls and UI are much more refined in my opinion. Pairing this with Home assistant. Its the perfect match. Plus if your using zones in your house. A ... show more

I’ve had mine for about a year now and it’s worked flawless from day one. Highly recommended. Phone app and Alexa voice command are so cool. I love controlling it when I’m not home and when I’m sitting on the couch I can either tell Alexa to change the temperature or do it on my phone. The daily programming feature is perfect as well. Install was easy as long as you follow the instructions. Great product. ... show more
